2. For smaller sums of money (e.g. coffee) you can pretty much assume the transaction to be confirmed once you see it on the network. To be really, really sure the transaction is confirmed and money is yours, you have to wait about an hour.
3. Indeed, Bitcoin fluctuates, you need to peg it to your expenses which is usually your local currency. That doesn't mean you must convert it to that currency. You can incorporate this into your payment button. But yes, this is a downside.
Maybe it's worse for PhDs or at better (research) universities?
The sad fact is that you simply cannot handle root shell to an average consumer. The only result of that is a security hole because the user is grossly uneducated (the question whether he should be educated is for another time).
Regarding the bootloader lock/root, you have to commend Google for offering great, and easy to unlock & root phones off the shelf. The fact that US cellular market is screwed with subsidies and carriers making it hard to root phones is a whole different issue - that's really not Google's fault. It's also definitely not the case elsewhere (e.g. in Europe, where my experience comes from).
And I also think this is a much better state than if all those phones run Windows ;)

That said, I really doubt that these classes will remain free. (Especially with likes of Hardvard and MIT.)
